I have been working on getting my timing set for a couple hours now and I think I am either going crazy or there is a problem or something I am not aware of.
I get the enigne warmed up
I set the idle mixture to around 14:1 (I am using an O2 sensor)
I get the idle to be around 1000 RPM (big cam)
I looked at the timing and it is 20 degrees (engine builder recommends this)
5 minutes later, the idle drops about 50-150 rpm
I check the timing and it is now 10 degrees
I increase the idle back to 1000
still 10 degrees
I set it to 20 degrees and lock it in again
I rev to 3200 and get onlt 28 degrees
Back to idle, but now it's around 1100
timing is at 24 degrees
no matter what I tried or what springs I use, it never comes back down to the set timing. and it takes about 5 minutes for it to come down any degrees
I called MSD and they had me check the bushings under the weights and that it all moves freely, and it all moves just fine and I even dapped a little
oil on the pivit areas and no difference.
Do I just have a bad distributor (only 800 miles on it)? Anything I'm missing?
